Re: Can BLC3000 Chassis power plug into NEMA 5-15 120V 15amp home/office power outlet in Canada

Depending on whether your 4 blades are tiny half-height BL460c's or power-hungry full-height BL870 Itanium blades, the number of power supplies required can be different. Google for "HP Power Advisor" for a program that can give you an estimate of the power requirements based on your exact configuration.

Low-line and high-line identify only the voltage: low-line means 100-120V, while high-line means 200-240V. The plug type will depend on the amperage it's rated for.

The power usage of a blade chassis depends heavily on which blade models are plugged into it, how many of them there are, and how hard they're working. So the 800 - 900 watt value is the maximum for a particular power configuration. With 120V, 900 Watts divided by the voltage works out to 7.5 amps... so you could even plug two power supplies to one 15amp circuit. To support all 6 power supplies at full power, you should have at least three separately-fused 15amp circuits available for the exclusive use of your c3000 enclosure. Of course, a separate circuit for each power supply would be preferable if you're looking for fault-tolerance.

The HP specs page you included says "optional low-line power cords for wall outlets" and that the c3000 chassis has standard (IEC 60320) C14 power input connectors, so it's just a matter of finding or ordering the right power cords. And HP definitely has a lot of power cord options available:
